Greenbelt’s 48-acre reservation adjoins the city-owned Den Rock Park, a 120-acre natural wooded setting which traces its history to Indigenous People and the first European settlers in Massachusetts.
Den Rock itself is a massive granite rock formation located on the border of Andover and Lawrence, a popular spot for rock climbers.
Well-marked trails, rock outcroppings, beaver ponds and the adjacent Shawsheen River make this an excellent property for hiking, rock climbing, birding, and simply enjoying nature.
Archaeologists believe its gently sloping, well-drained ground furnished an ideal landscape for Native American campsites and villages. Fire-blackened quartz indicates its small caves could have been used for shelter and food storage according to the Bulletin of the Massachusetts Archaeological Society.
The discovery of over 1,000 shards of pottery during archaeological excavations decades ago provides evidence that the land’s minerals were used to make earthenware vessels. Glass and iron gun parts in the area are likely remnants of the early European settlers, according to the Massachusetts Archaeological Society.
Purchased in 1877 for a cemetery but then changed into a city park in 1896, Den Rock was improved in the 1930s by workers with the Civilian Conservation Corps who installed rock steps, two amphitheaters, a boardwalk, and numerous trails.
For bird-watchers, the trails offer opportunities to observe an abundance of both migratory and resident bird species in the park, including many spring warblers, many woodpeckers, herons and egrets in the wetlands, belted kingfishers, and birds of prey like the red-tailed hawk.
A variety of woodland animals also call the park their home, including deer, fox, fisher, coyotes, beavers, and racoons.
Native tree species include white and red oak, gray birch, scotch and white pine, poplars, and red maples. The wetlands and Shawsheen River banks are home to cat-tails and many rushes and sedges.
In December 2020, Greenbelt acquired 48 acres in Andover and Lawrence from the Merrimack River Watershed Council (MRWC).
MRWC had owned and managed the land since 1999, and we're grateful for their stewardship.
Greenbelt's ownership of the land brings the resources and experience of the organization to bear on a significant community resource. We look forward to working with local partners, including Groundwork Lawrence, the City of Lawrence, the Andover Village Improvement Society (AVIS) and other groups.
We encourage you to visit the Groundwork Lawrence website for a comprehensive description of Den Rock Park's history, trails and natural resources.
